SPECIFICATION forming part of Letters Patent No. 396,946, dated January 29, 1889.

Application filed August 13, 1888. Serial No. 282,522. (No model.)

To [all 2071/0112, it may concern:

Be it known that we, JOHN C. MILLER and AUGUSTUS H. J ONES, of Meriden, in the county of Newl-l'aven and State of Connecticut, have invented a new Improvement in Lamp-Stand ards; and we do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact descripeonstitnte part of this specification, and represent, in

Figure 1, a sectional side view of so much of the standard as necessary to illustrate the invention, and showing the cushion as attached tothc stationary tube; Fig. 2, a modification showing the cushion as applied to the adjustable tube.

This invention relates to an improvement in that class of lan1p-standards which are designed to rest upon the Floor and support a lamp upon the upper end. These standards are usually composed of two tubes telescopically arrai'iged, the outer tube supImrted upon the base, while the inner tube carries the lamp and is adjustable in the outer tube, so as to permit the lamp to be adjusted. to different elevations. 'lhese'standards are usually provided with a device for interlocking the two tubes, so that the lamp may be held at any desired elevation; but a difficulty is experienced in such device, owing to the fact that when disengagement is made between the two tubesthe inner tube being free to slide downward unless held by handthe lamp is liable to drop rapidly and with c011- siderable force, until the collar on the top of the adjustable tube, or the lamp thereto attached, strikes a collar on the top of the outer tube, which brings the lamp to a sudden stop, so sudden as often to throw the shade or chimney from the lamp or otherwise derange the lamp.

The object of our invention is to provide a construction which will preventsueh accidents; and it consists in providing an elastic cushion in the collar of the standard, upon which the descending tube and lamp will come to a bearing, and so that the cushion will make such contact or bearing so easy as 1 standards. tion of the same, and which said drawings 3 to avoid the diificultics which we have mentioned.

In the best construction of the invention, A represents the outer tube, which is made to the base, and B the inner tube or rod adjustable within the tube A, and so as to slide freely up and down, the said tube B carrying the lamp, as usual in this class of lVe illustrate only a portion of he two tubes, but sufficient for the full understanding of the invention. \Ve also omit the engaging devices usually employed between the two tubes, as any of the many known devices for this purpose may be employed.

To the upper end of the stationary tube A a collar, 0, is firmly secured, so as to become substantially a part of that tube. This collar has an internal diameter above the tube A somewhat larger than the inner tube, B, and the collar is recessed upon its inner side to form a s n-ing'chamber, D. it-11in the collar a sleeve, E, is arranged, which extends to the spring-chamber, and constructed with an annular flange, h, which projects into the spring-chamber, and between the flange F and the bottom of the spring-chamber we arrange a spring, of any suitable character, upon which the sleeve E will rest, and when so resting the upper end of the sleeve E projects above the collar D, as clearly seen in Fig. 1.. The spring permits the collar to be compressed should force be applied to its upper or projecting end. Under this construction if the inner tube, B, descend, the collar on the upper endof the tube, or the lamp attached thereto, will strike upon the upper end. of the sleeve E, and the force of the blow will be met by the spring G in the chamber below the sleeve, and so that the sleeve will yield under such blow and thereby avoid the shock which occurs when there is no yielding cushion upon which the blow of descent may be taken.

In Fig. 1 the collar )is represented as made in two parts. This is for convenience of construction. The several parts are united after the introduction of the sleeve and spring, so as to become practically one.

We have represented the cushion as formed upon the stationary part of the standard; but 100 it will be evident that it may be reversed and made upon the adjustable portion of the standard, as seen in Fig. 2, so that the sleeve will meet the collar on the stationary tube as the inner tube descends.

\Ve claim 1. In a lamp-standard composed of a stationary tube, with an inner tube or red workin g telescopically therein, the said inner tube carrying the lamp,'the con'lbination therewith Of a sleeve surrounding the inner tube and Vertically movable, with a spring arranged to yielding'ly support said sleeve, substantially as.deseribed,.and whereby said sleeve forms an elastic cushion upon which the force of the descending lamp will be met.

2. In a lamp-standard composed of an outer tube, A, and a rod or inner tube, B, telescopically adjustable therein, the said rod or tube B carrying the lamp, a collar, D, fixed to the upper end of the said stationary tube, said collar constructed with an annular spring-chamber upon its inner surface, and a sleeve, E, in said collar surroundingthe adjustable rod or tube and projectin above said collar, with a springin the chamber of the collar below said sleeve, substantially as and for the purpose described.
